Encoding

Understand Base64 encoding

Encode and decode safely without corrupting data.

When Base64 is useful

Use Base64 for transport and embedding, not for security.

Step-by-step

Choose encode or decode, paste input, then verify the output matches expected bytes.

Avoid pitfalls

Check for URL-safe variants and padding issues.

Checklist

  • •Confirm charset.
  • •Watch URL-safe format.
  • •Validate output length.
